' THEADJUSTABLE TELEPHONE SUPPORT COMPANY, OF BOSTON, MASS.

. Malden, in the county of Middlesex and State SUPPORT FOR TELEPHONES] SPECIFICATION forming part of Letters Patent No. 289,180, dated November 27, 1883.

Application filed April 6,1883. (Noruodold T (tZZ whom it may concern:

Be it known that I, JAMES TREGURTHA, of

of Massachusetts, have invented certain new and useful Impro vem ents in Su pp orts or Stands for Telephonic and other Instruments, of

which the following is a full, clear, and exact description.

Thisinventiou relates to a bracket more par; ticularly designed for carrying telephonic ina,strumentstransmitters and receivers, either or both-although it is also applicable to microscopie and other instruments.

The object of this invention is-to provide bracket for carrying such instruments which sh all be capable of ready and easy adjustment,

and thereby, with a suitable attachment or :1 connection between the instruments andthe it bracket, enable the instruments to be most readily and easily adjusted in position for con- "Venient use of either or both by operators.

This improved bracket, in substance, is composed of two arms, which are jointedat oneend of each, so that they can be placed in line with or at an angle to each other, and are jointed at the other end of each, the one arm to a plate or other part suitable to be attached to, the side wall of a room or other fixture, and the other arm to a standard or post, to

.be carried by said bracket are to be connected which the telephonic or other instruments to in any suitable manner, all substantially as 1,hereinafterdescribed, reference being had to thisimproved bracket is shown the accompanying plate of drawings, in which Figure 1 being a perspective view with some opartsbroken out and in section; Fig. 2, a plan auview; Fig. 3, a side elevation with some parts in vertical section; and Fig. 4 is a detail view of amodification, to be hereinafter described. In the drawings, A represents a plate adapted to be fastened by screws ,or other suitable fastening devices to the wall B of a room or other suitable fixture.

O is a flat post or stud attached to and proj eoting at right ngles horizontally from the inplate A when said plate, is fixed to the wall g-qB. To this post 0 one end of an open tubulan arm, D, is doubly jointed, asat E, and this arm D at its other end is jointed, as at F, to.

strument, such as a receiver, K, and a trans mitter, L, which are connected to said rod by arms V and joints R S T U, substantially the same as described and shown in the specification and drawings in another application for Letters Patent of the United States made by me, and filed on March 26, 1883; and as such connection of the instrumentswith said rod 0, letteredthe same in said application, forms of itself no part of the present inven tion, but is shown and referred to only as one and a desirable way of connection for the instruments with said rod-standard, it is not deemed necessary to herein more particularly describe it.

The double jointing at E of the tubular arm D to the plate-post C, and at H of the tubular arm G to the rod 0, carrying the telephonic instruments, is by means of joints M and M and N and N", respectively. In eachinstanee each j oint M M and N N is composed of three separate lifts or leaves, a b c, of a cireular-disk being turned or rotated upon said axial bolt.

The outer lifts or leaves, a c, of each of the joints are locked together byapin, g, fastened to one and entering loosely into a seamen, of the other, and located in a lug, J, of one outer disk, and in an arm, hereinafter referred to, of the other outer disk. The said lugs and arms project from the edge and one side of the lifts, and as a consequence, witheither of said outer lifts fastened or held against turning in any manner, the other one thereof will be correspondingly held. against .move; ment; but if neither thereof is; so :fastened,

. or post of said plate A, and the upper outer lift, a, of said joint M connects by an arm, I, to the middle lift, 1), of the joint M", which joint M is at right angles to the joint M upon the wall-plate A. The joint M, by one outer lift, a, is connected by an arm, m, in extension of the tubular arm D, to one end of said tubular arm D, and this tubular arm by an extension, at, at its other end is connected to the outer lift, 0, of the three lifts a, I), and c, which make the joint F between the two tubular arms D G, and said joint is the same in construction and arrangement of parts as previously described for the other joints, M M N N". The middle lift, 1), of the joint F is connected by an arm, q, in extension of the tubular arm G, to one end of said tubular arm G, and this tubular arm has an extension, 1-, at its other end, and is connected by said arm or extension r to the middle lift, b, of the joint N, connected by one of its outer lifts, a, to the middle lift, 1), of thejoint N,

' each other, as before stated, for the joints M and M between the wall-plate A and tubular arm D, and as a consequence the planes of rotation of the two joints of each set of double joints are at right angles to each other. The axial bolt f of the joint ill at wall-plate A is made tubular, for the passage of the electric wires through it, and thence through the tubular arm D, to and through the tubular arm G, to and through the tubular arm 7 of rod-standard O, to the transmitter and receiver.

The arms D G-prcferably tubular, andj oi nted atone end to each other, and at the other end of each doubly jointed, the one, D, to a wall plate, A, or equivalent part, and the other, G, to a rod-standard, O, or equivalent part, to which the telephonic or other instruments are connected-constitute in substance abutment of the pin 9, connecting its outerlifts, a .b, againstthe arm which connects a .liftof; said jo nt either to another of said joints next in order of arrangement or to one team of the tubular arms D G, as the case may be, and that as a consequence there can be no possibility of an entanglement and twist of the electric wires about the exposed parts of the bracket; third, that the double jointing of the tubular arms D G, together with the joint of the arms to each other, such as herein described, obviously enables the bracketto be brought to almost any position which may be desired, thus enabling, even if such a bracket is used alone with telephonic instruments, such instruments to be most easily and readily located for convenient use by operators. Of course, with mechanism such as shown as connecting the rod-standard O to the telephonic instruments, and which, as before stated, is embraced in another application for Letters Patent of the United States, filed March 26, 1883, it is plain the scope and variety of ad j ustment as to position for the telephonic instruments will, with the adjustments from brackets herein shown and described, be greatly increased and augmented.

p p are eyes or loops lastened to parts of the bracket herein described, for guides to the passage of the electric wire through the parts of the bracket, as has been herein described.

The tubular arms may be connected to each other by a double joint, as has been described for the connection of the other ends of each of said arms; and, again, the connection of said arms to the wall-plate A and to the rodstandard 0, either or both, may be byasingle joint-such as the joint F, described for connecting the two arms D G togetherin lieu of a double joint, and yet secure in substance the objects of this invention; but it is preferable to joint the parts 'as has been particularly described, as by such jointing the greatest variety of adjustments is obtainable.

In Fig. 4: (being a view of the joint of the bracket detached) an outer lift of said joint is shown as provided with an arm, j, having thnmb-screw k in position to be set against and loosened from the edge of the middle lift of said joint, and thereby enabling said joint to be fixed against and released to movement, which, as is obvious, in some cases might be advantageous to use.

An arm and thumb screw, as above described, may be also applied to any one or more of the other joints of the bracket, or-of the joints of the arms connecting the telephonic instruments to said bracket, and the application of said arm and thumb-screw is to be in such relation to the movement of the joint as not to interfere in the smallest degree possible with the movement of the joint.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

l. A bracket for carrying telephonic and other instruments, composed of arms D and G, jointed together, and one jointed to a plate,

A, and the other to a standard, 0, in combination with instruments-such as a receiver,

K, and a transmitter, L-carried at opposite ends of said standard 0, substantially as described, for the purpose specified.

2. A bracket for carrying telephonic and other instruments, composed of arms V V, constructed to be lengthened and shortened, and jointed to a common standard, 0, which is jointed to an arm, G, in turn jointed to an arm, D, jointed to a plate or support, A, in combination with instrumentssuch as a receiver, K, and a transmitter, L-carried by said standard 0, substantially as described,

for the purpose specified.

3. A bracket for carrying telephonic and other instruments, composed of tubular arms D and G, jointed together, and the one, D, j ointed to a plate, A, and the other to a rod-standard, O, in combination with the guide-eyes 12, attached to the parts of the bracket, substan tially as described, for the purposes specified.

4:. A bracket for carrying telephonic and other instruments, composed of arms D and Er, jointed together by a joint in lifts (6,1), and c, and the arm D, doubly jointed by joints M and M", each made of lifts a b c, to the plate A,

and the other arm, G, doubly jointed by joints N and N each made of lifts a, b, and c, to rodstandard 0, to which the telephonic or other instruments are connected, substantially as pendently of the middle lift, and for said middle lift to turn upon said pin independently of the outer lifts, of an arm attached to one of the outer lifts, and carrying a thumbscrew or other stop-in position to be adjusted from the exterior of the joint, and thereby brought to a hearing against the edge of middle lift, 1), substantially as described, for the purpose specified.

In testimony whereof I have hereunto set my hand in the presence of two subscribing
